CPT® Code 45384

A flexible colonoscopy is a diagnostic and therapeutic procedure that involves the insertion of a colonoscope into the rectum and advancement through the colon to the cecum or the terminal ileum. This procedure is performed to visualize the mucosal surfaces of the colon, allowing for the inspection of any abnormalities such as tumors, polyps, or other lesions. During the colonoscopy, air insufflation is utilized to separate the mucosal folds, enhancing visibility for the physician. When a lesion is identified, the procedure can involve the removal of the lesion using hot biopsy forceps, which is specifically indicated by CPT® Code 45384. The hot biopsy technique employs insulated monopolar forceps that not only excise the tissue but also cauterize it simultaneously, making it particularly effective for small polyps and vascular ectasias. This method contrasts with the snare technique described in CPT® Code 45385, where a wire snare loop is used to remove larger lesions. After the removal of the lesion, the endoscope is withdrawn, and the mucosal surfaces are re-examined for any signs of complications such as ulcerations or bleeding.
